Heddle frame with vibration damper element

Abstract

A projection extending from a side support for defining a detachable edge connection at the heddle frame, which detachable edge is clamped down by a clamping screw carried in a hollow frame stave. A vibration damper element is positioned between the side support and the projection and is connected thereto preferably by bonding. The vibration damper element is an elastomer and has a strip-like shape having a width corresponding with the width of the side support. The side support is connected to the frame stave at each edge connection via the vibration damper element, and vibrations occurring in high speed weaving machines, which vibrations can lead to material ruptures at the side support, are dampened.

What is claimed is: 
     
       1. A heddle frame including spaced side supports and frame staves extending between the side supports, the frame staves having hollow portions, said frame comprising a projecting member carried by and extending laterally from a vibration damper element attached to a surface of a mutually adjacent side support and received within a hollow portion of a frame stave, said vibration damper element positioned between and along at least the entire length of the mutually adjacent surfaces of the projecting member and the side support to space said member from said support. 
     
     
       2. A heddle frame according to claim 1, wherein the vibration damper element is a strip of elastomeric material having a substantially constant thickness. 
     
     
       3. A heddle frame according to claim 1, wherein the projecting member includes a planar base part having a length in a direction parallel to the side support greater than a corresponding dimension of the projecting member, and wherein the vibration damper element extends along substantially the entire planar base part of the projecting member. 
     
     
       4. A heddle frame according to claim 1, wherein the side support and the projecting member include opposed, non-planar surfaces between which the vibration damper is positioned to space the non-planar surfaces from each other. 
     
     
       5. A heddle frame according to claim 4, wherein the opposed surfaces are each V-shaped in cross section. 
     
     
       6. A heddle frame according to claim 4, wherein the opposed surfaces are each U-shaped in cross section. 
     
     
       7. A heddle frame according to claim 1, wherein the vibration damper is adherently mounted to each of the side support and the projecting member. 
     
     
       8. A heddle frame according to claim 1, wherein the vibration damper is cemented to the side support and to the projecting member.
